Programming Theft Deterrent System Components (Domestic Vehicles): Notes
IMPORTANT:
When replacing a engine control module (ECM) with a GM SPO Replacement Part, insure the procedure to setup a new ECM is performed prior to the 10-minute relearn procedure or the 30-minute relearn procedure.
IMPORTANT:
- When replacing a remote control door lock receiver (RCDLR) with an GM SPO Replacement Part you must replace the entire kit this includes the RCDLR and two key fobs. The RCDLR key fobs are pre-learned to the new RCDLR additionally, the existing engine control module (ECM) must learn the new password of the replacement RCDLR.
- When replacing an ECM with a GM SPO Replacement Part, the new ECM will learn the incoming password of the RCDLR immediately upon the next ignition switch from OFF to CRANK. A ECM which had been installed in another vehicle will have learned the theft deterrent password of another vehicle's RCDLR. Perform either the 10-minute relearn procedure or the 30-minute relearn procedure to learn the password of the current vehicle's RCDLR.
